I'm considering buying an Aguilar TH500 to go with my TC RS210 and RS212. My main question is, are these compatible in terms of wattage and ohms? I play in a super loud reggae band where I've been driving those cabs with an RH450, and I'm looking for something that can replace that. I'm also hoping to use it with upright into just the RS210. I go all cross eyed when I try to understand how ohms work. Can someone help out the mathematically challenged and tell me if this seems like a good idea?
